Overview
- Marc Rosenblum announced over the weekend that he has left his post as executive director of the Office of Homeland Security Statistics and said he was “thrilled to end” his relationship with the administration while condemning what he called a war on immigrants, feds and facts.
- Rosenblum ran the office that aggregates DHS-wide numbers and had pledged in 2023 to publish faster, more detailed data, but the office’s public portal for ICE detentions, Border Patrol encounters and repatriations has not been updated since February 11, 2025.
- DHS declined to comment on personnel matters and said only that people are entitled to their opinions, a brief response that reporters say does not address questions about the department’s data releases.
- Analysts, advocates and watchdog groups say the lack of authoritative, regularly updated DHS statistics has hampered accountability and prompted FOIA requests and lawsuits to recover enforcement figures that the department no longer posts.
- Rosenblum’s exit is part of a string of senior departures at DHS and revives concerns about the real-world effects of large-scale enforcement, including disruptions to families and labor markets that Rosenblum previously warned about.
